Noctua NF-P14s redux-1500 PWM, High Performance Cooling Fan, 4-Pin, 1500 RPM (140mm, Grey)

Ive just had one of these replaced by Amazon (May 2021) after finding the first one to have completely unacceptable levels of motor or bearing noise (almost certainly the latter as I tested with pure DC, no PWM circuitry involved) even at 7v or c. 800 RPM.

Really fast!

Installed and got them running. They scale rather well when using PWM and Ive seen good temps generally

I purchased this to replace a top case fan that would constantly vibrate and sometimes make violent sounds during its revs. Initially in Bios, the Fan was running at max RPM, which I found odd. However, I was able to decipher that the reason for this was because the PWM feature of the fourth pin was disabled by default ( for some reason ). With this turned on, and tested, I can just barely make out the sound of the fan when I focus on it, which I think is phenomenal. Especially under game load, the noise level of the fan was never really as distracting as the one I had in my case prior. Very much recommended.. ESPECIALLY at the price point.

After an initial debacle with Amazon of having received a clearly used, 120mm Cooler Master fan (in a 140mm Noctua Redux box that had a new sticker on it), I received the correct Noctua Redux fan. I should note that the process was simple and Amazons customer service was exemplary in this situation - it was my first issue like this in ~10 years of using Amazon. A word of caution: because these fans come in unsealed packaging they could be swapped with other products or used versions unknowingly to the buyer. I recorded myself opening the second one in case that happened again. I did not even think of this a few weeks prior when I ordered/received a 120mm Redux fan that I used as rear exhaust.

i have the Corsair H115i RGB AIO 280mm radiator it had the dual 140mm fans that came with it and theyre decent but silent and maxxed out at barely hitting 1000rpms can hardly feel and air pressure behind them so i replaced them with these and theyre also silent from low to mid range and very subtle when full speed almost 1500 rpm but at low speed theyre giving more static pressure and more volume than the corsairs did at full speed,i have my setup in a Tt V200 RGB case with 280mm radiator mounted in front for cool intake air across radiator and the stock 3 120mm RGB fans case mounted in front for a push ull set up ,, believe the hype these are awesome temps are lower across the board

Quiet and move a lot of air.

Fantastic fan. Its larger than you might expect (140mm) so it pushes huge amounts of air while also being nice and quiet. On top of the high quality, the customer service is phenomenal! Would definitely recommend to a friend... or stranger.

Esta bien grande y sin ruidos

Super quiet and looks great!!
